Embodiment 1

[0021] A special feed for freshwater grouper, which consists of the following components by weight: 48 parts of fish meal, 15 parts of soybean meal, 6 parts of casein, 3 parts of yeast, 21.4 parts of subflour, 4 parts of multivitamin, and 0.8 part of fish oil , 0.8 part of soybean oil, 1 part of sodium alginate.

[0022] The cultivation effect of the feed on freshwater grouper is investigated by the experimental method below.

[0023] 1 Materials and methods

[0024] 1.1 Test material

[0025] 1.1.1 Experimental fish and feeding management

[0026] The average body weight of the fish used in the test was 45.41±1.64g. The test was carried out in a cement pool, and 36 net cages (specification: 1×1×2m 3 ). The experiment was divided into 12 groups with 3 repetitions in each group. 30 tails per cage. Before the start of the experiment, the fish were acclimatized for 7 days and fed twice a day (9:00 in the morning and 17:00 in the evening). The daily feeding amount is 1%-3%...

Embodiment 2

[0080] A special feed for freshwater grouper, which consists of the following components by weight: 48 parts of fish meal, 15 parts of soybean meal, 6 parts of casein, 3 parts of yeast, 21.4 parts of subflour, 4 parts of multivitamin, and 0.8 part of fish oil , 0.8 parts of soybean oil, 1 part of sodium alginate, 5 parts of distiller's grains, 8 parts of red yeast rice, 7 parts of purple sweet potato powder, 5 parts of Poria powder, and 12 parts of jujube juice.

[0081] On the basis of the above technical solutions, the following conditions are met:

[0082] The Duowei Duo mine contains calcium carbonate, ferrous fumarate, zinc citrate, selenium-enriched brewer's yeast and vitamin C.

[0083] Each kilogram of the multivitamin contains the following substances: vitamin A 900000IU, vitamin D200000IU, vitamin E 4500mg, vitamin K 3220mg, vitamin B 1320mg, vitamin B2 1090mg, vitamin B5 2000mg, vitamin B6 500mg, vitamin B12 1.6mg, Vitamin C5000mg, pantothenic acid 1000mg, folic ac...

Embodiment 3

[0087] A special feed for freshwater grouper, which consists of the following components by weight: 48 parts of fish meal, 15 parts of soybean meal, 6 parts of casein, 3 parts of yeast, 21.4 parts of subflour, 4 parts of multivitamin, and 0.8 part of fish oil , 0.8 parts of soybean oil, 1 part of sodium alginate, 5 parts of distiller's grains, 7 parts of purple sweet potato powder, and 12 parts of jujube juice.

[0088] On the basis of the above technical solutions, the following conditions are met:

[0089] The protein content in the feed is 48.5% (w / w), the fat content is 8.5% (w / w), the ash content is 3.2% (w / w), and the moisture content is 10.5% (w / w).

Abstract

The invention provides feed special for cichlasoma managuense. The feed comprises 48 parts of fish meal, 15 parts of bean pulp, 6 parts of casein, 3 parts of yeast, 21.4 parts of wheat middling, 4 parts of multi-vitamin polymineral, 0.8 part of fish oil, 0.8 part of soybean oil and 1 part of alginic acid. The influence on the cichlasoma managuense culture effect by feed nutrients is researched through an experimental method, the fish weight gaining speed is directly directed by limiting the content of crude protein and crude fat in the feed, and the feed has a prominent promoting effect on the weight gaining speed, the content of intestinal tract digestive enzymes and muscle nutrient components when the protein content, the fat content, the ash content and the water content are 48-48.5% (w / w), 8-8.5% (w / w), 2.7-3.2% (w / w) and 9.5-10.5% (w / w) respectively. In addition, it is accidentally discovered that the growth speed of cichlasoma managuense is obviously increased when red kojic rice, or poria cocos powder or wild jujube juice are added additionally. Based on the beneficial discovery, the composition of the nutrient components is further optimized, and a better culture effect is obtained.

Description

technical field [0001] The invention relates to the technical field of freshwater fish culture, and further relates to the nutrition research of freshwater grouper, in particular to a special feed for freshwater grouper. Background technique [0002] Freshwater grouper (Cichlasoma managuense), belongs to perciformes (perciformers), family Cichlaidae (Cichlaidae), genus Cichlidae, and its origin is Central America. Introduced into Taiwan, China in 1988, and introduced to the mainland from Taiwan, China in 1996. The freshwater grouper has a spindle-shaped body, with black stripes on the side of the body, a melanin block in the center of the stripes, and bright stripes on the body. The pectoral fin is light yellow, the pelvic fin dorsal fin and anal fin have black markings, and the caudal fin black stripe is perpendicular to the body. Freshwater grouper is a high-quality freshwater fish with high nutritional value. Its meat is tender and delicious, and it also has certain orn...
